Toyota and Mazda led from the front in July, contributing towards the record 92,754 new vehicles sold in Australia during the month, according to official VFACTS data.
The previous July peak of 92,308 units was set in 2015, meaning the 2017 result joins three other months that have set new individual records this year.
A monthly sales total of 17,931 saw Toyota achieve its best July since last decade, falling short of its record 2008 effort where 20,521 examples were moved.
Over July last year, Subaru impressed with its sales soaring by 27.1 per cent.
Mazda also set a personal July record, with 9528 units shifted due to its reinvigorated Mazda3 small car, which enjoyed a 64.3 per cent sales increase over the same month last year when it was about to welcome a mid-life update.
Kia set a record for the month, with its volume increasing by 20 per cent to 4265, while Mitsubishi sales swelled by 11.2 per cent to 6020.
